RY-LOCK COMPANY, LTD., 013 RENO, NEVADA, A CORPORATION OF NEVADADOORLOGK The inventionrelates to door locks of the latch bolt type, andthe present embodiment of the invention relates more particularly to.,,such types of locks having a rotatable and "axially displaceable"spindle for actuating the latch bolt.

An object of the invention is to provide a lock of the class describedhaving operating means therefor at each side of the door which may berendered inoperative to effect the retraction of the latch bolt.

Another object of the invention is to provide a lock of the classdescribed having op- ..erating mechanism of such design and constructionthat the parts cannot be distorted to effect the operation of the lockeven upon the application of great force thereto.

A further object of the invention is to pro- --.vide a lock of the typein which the axial position of the spindle controls the operationthereof, having key controlled means for locking the spindle againstaxial displacement when positioned to prevent the opera- .tion of thelock.

A still further object of the invention is to provide a lock of theclass described, in which the dismantling of the lock is absolutelyprevented when the lock is positioned to prevent operation. from bothsides of the door.

The invention possesses other objects and features of advantage,some ofwhich, with the foregoing, will be set forth in the followingdescription of the preferred form of the invention which is illustratedin thedrawings accompanying and formingpart of the specification. It isto be understood, howview of the lock positioned in a door.

The present embodiment of my invention is incorporated in a lock 12disposed in a suitable cavity 18 provided in the free edge portion 1 1of the door 16, which is arranged to be operated from the inner andouter sides of the door by means of a knob 17 and a thumb lever 18. Thelock is provided with a bolt 19 which is arranged to normally ex- 7 tendfrom the outer end of the bolt casing 21 mounted in the door edge 14.

Slidably mounted in the casing 21 is a bolt yoke or latch plate member22 for actuating the bolt, such member being here shown hollow and is ofgenerally rectangular outline, and being urged to assume and maintain anouter position by reason of a spring 23 operatively engaged behind it.Journalled in the casing 21 to extend horizontally therethrough is alatch actuator 24: having ex tending therefrom intermediate the casingwalls an arm 26 arranged for engagement with the lat-ch plate 22 in sucha manner that a rotation of the actuator from the normal position shownin Figure 3 will effect a retractive displacement of the latch bolt.Preferably, and as shown, the actuator arm 26 is arranged for engagementwith the latch plate both at the upper and lower sides thereof wherebyrotation of the actuator in either possible direction may retract thelatch bolt.

Extending axially through the actuator is an opening 27 arranged for theslidable reception of a spindle 28, the opening and spindle being oflike polygonal section whereby rotation of the actuatormay be effectedby rotating the spindle. Rotation of the latter from the inner and outersides of the door may be effected through the medium I of the knob 17and thumb lever 18 which are operatively connected to the spindleadjacent the inner and outer ends thereof.

The spindle is arranged within a cavity portion 29 which extendstransversely through the door and combines with the cavity 13 in whichthe latch-plate is disposed. Arranged at opposite ends of the cavity 29and disposed against the inner and outer sides of the door are plates 31and 32 which serve to support the lock on the door. The plates aresecured together by means of screws 33 which extend from the plate 31and engage in the extensions 34 fixed to'fthe plate 32. The plate'32 isin turn fixed to the escutcheon plate 35 which is arranged on the outerside of the door and encloses the plate and the lock mechanism on theouter side thereof. 7 f 7 The spindle is formed of two sections 36 and37, having a screw threaded connection, such as indicated at 38, wherebyone section mayrotate with respect to the .other, the portions of thesections adjacent their point of connection being here arranged to lieat all times Within the opening 27 ofthe bolt actuator 24. In thepresent embodiment of the invention the spindle is arranged to occupydifferent longitudinally spaced. positions, and means are thereforeprovided for supporting the spindle for such movement as well as topermit the rotation thereof in said positions. As shown in Figure 1, the

spindle section 37 is provided with ajour- 1 ha l :39 which is mountedfor rotatable and axial movement in the bearing 40 allixed to the plate32. Preferably formed integral with the spindle section and disposedinwardly of the journal 39 is a body 41 comprising a cylindrical portion42 and a gear 43, the outside diameters of which are here shown equal.Positioned at the side of the body 41 and mounted to move tangentiallythereof is a gearrack 44 arranged for rotating the gear 43 when the rackis engaged therewith. As previously stated the spindle is arranged to bemoved longitudinally from one position to another, and in one of saidpositions the gear will be opposite .the rack while in the otherposition, which is indicated inFigurel, it will be removed therefrom. Itwill thus be evident that when the rack is opposite the gear,'the thumblever 18 which is'operatively connected to the rack, may be depressed soas to raise the rack and thereby effect a rotation of the spindle andthe consequent retraction of the bolt. Normally, as shown in Figure 7,.the rack is retained i'n adepressed position by means of a spring 46attached to the thumb lever, so

will be understood, is confined to movement in a single tangential line,and it will thus be" noted that when the portion 42 is opposite therack, said portion will be in the direct path of the rack teeth andmovement of the rack will not be possible. In this manner when thespindle is thus disposed, not only will the rack be ineffective forrotating the spindle but the rack thumb lever, will be locked againstmovement.

While actuation of the latch bolt by means of the thumbleveris thuseffectively prevented when the spindle is positioned to present theportion 42 to the rack, key-controlled means are provided by which thespindle, while so disposed, may nevertheless be rotated from the outerside of the door. Arranged within the escutcheon plate 36 is a tumblerbarrel 49 having a passage 51 for the proper key 52. Slidably fixed tothe outer end of the spindle but rotatable therewithis a key tip;receiving member 53 preferably extending partly into the passage 51.Thereceiving member 53 is provided with suitable notches so that whenthe key shank is inserted into the passage and the key tip is seated inthe notches, the spindle may be rotated upon the turning of the key, itbeing noted that the rack and portion 42 offers no resistance to suchturning...

The spindle is, in the present embodiment of the invention, normallyurged to assume what may conveniently be termed the retracted position,that is, the position in which the gear is inoperatively disposed to therack. This is preferably. accomplished independently of the, latch boltspring, and, as here shown, the same is elfectedj by means of .a spring54 arranged within thespindle and interposed". between the key. tipreceiving member and a wall of the spindle.

The knob 17, as previously stated, is preferably directly secured to theinner end of the spindle and may be utilized both for rotating 7 thedoor. In order that the 'knob may be held against turning when thespindle is in retracted position, to thus denote that retraction of thebolt by the'thumb lever is not per-f mitted,or, in other words,:that thedoor is locked fromthe outside, means are provided for causing thespindle section 36 to be held against rotation when thei spindle is inretracted position but permitting the turning of the knob to rotate thespindle when the latter is in protracted position. As will be seen fromFigure 1, the spindle-section 36 extends through an opening 59 which isformed in the side plate-31- When the spindle is in the retractedposition, one portion 61 of the section. engages in the, opening,

whereas when the spindle is in protracted pwithin the opening. Theopening 59 and portion 61 in cross section are of the polygonal form sothat when in the retracted position of the spindle the section 36 cannotbe rotated. The portion 62, however, is round or otherwise formed sothat it may rotate freely within the opening. It will thus be clear thatwhen the spindle is protracted the section 36 is free to rotate and theknob may be turned to retract the bolt.

, It will be evident that in order to permit the retraction of the boltby means of the key 52 when the spindle is retracted, the section 36 ofthe spindle must not prevent the rotation of the bolt actuator 24:.Accordingly the portion 63 of section 36, which in the retractedpositionof the spindle is arranged to lie within the actuator opening,is formed round or otherwise reduced in cross sect1on so that theactuator may revolve thereabout. When, however, the spindle isprotracted, a polygonal portion 6 1 of the section 86, as well as saidportion 63,'will he within the actuator opening whereby rotation of theactuator by means of the knob 17 may beeifected. It maybe noted thatwhile the spindle s be1ng moved longitudinally from one posltlon toanother, either the portion 61 or 64 of the spindle section will berespectlvely engaged within the opening 59 or 27. In th s manner thespindle section will be retalned 1n proper position during the movementthereof and the portions 61 and 64 will be guided to proper engagementin said openings.

Means are provided operable from the inner side of the door, forretaming the spmdle 1n protracted position whereby the retraction of thebolt will be permitted by the mere use of the thumb lever or the simpleturning of the knob, in other words to render the door unlocked fromboth sides. Mounted for rotation on the knob sleeve 56, and as heregshown held against axial displacement thereon by means of the knobescutcheon 5S and an inner door escutcheon plate 66, 1s a posltioningmember 67 having a portion thereof concealed. within the escutcheon 66and protvided with a cam face 68. Fixed on the spindle against axialdisplacement but allowing the rotation of the latter relative thereto,is

a thrust member 69 having a vpair of arms 71 extending through openings72 of the plate 31 and arranged to engage the cam face 66. The member 67may be rotated from one pos1- tion to another whereby the cam incooperation with the member 69 will operate to force thejspindleforwardly from retracted topr'otra cted position and retain same in suchlatter position. With the spindle thus disposed, retraction of the boltmay be readily efiected by turning the knob or depressing the thumblever. By rotating the position- ,ing memberback again, the spindle willbe ably a button 7 3 is fixed to the member 67 so as to facilitate themoving of the member and at the same time affording a means of readilyindicating the position of the spindle.

Key-controlled means are provided which may be used for locking thepositioning member 67 against rotation when the spindle is in retractedposition so that when the door is locked on the outside but access issomehow or another secured to the knob or said member by a personstationed on the outside, retraction of the bolt from the inside will beimpossible without the use of a proper key. Fulcrumed to and lyingwithin the knob sleeve 56, is a lever 74-, one arm 75 of which isarranged, when the spindle is in retracted position, to engage in arecess 76 provided on the inner side of the member 67. With the leverdisposed within the recess, rotation of the positioning member will beprevented. The lever is urged to assume engagement in the recess by aspring 78, but such engagement is normally prevented by means of a cam79 bearing against the other arm 81 of the lever. The cam79 is fixed tothe inner end of a tumbler barrel 82 which is mounted within the knoband sleeve and which may be rotated by a proper key 83. The cam isprovided with a depressed portion 8% within which the arm 81 may seatwhen the tumbler barrel has been rotated to a predetermined position, atwhich time the arm 75 will engage the member 67 to prevent movementthereof and retraction of the bolt. With the lever thus engage-d withthe positioning member, release of the latter can only be effectedthrough means of the proper key.

The sleeve, as previously stated, is secured to the spindle by means ofa screw 57, access to which is afforded exclusively through an opening86 provided in the positioning member 67. The opening 86 is sopositioned on the member that it will be aligned with the screw onlywhen the spindle is in protracted position, and thus when the member isrotated to place tl e spindle in retracted position, the screw andopening will have moved completely out of registration. In this mannerit will be evident that when the positioning member has been locked bythe use of the key, removal of the knob from the spindle to effect adismantling of the lock sufficient to permit protraction of the spindlewill be absolutely prevented.

It will be noted that the lock of my invention, when assembled on thedoor, is without any visible means of attachment between the parts orwith the door, and in connection with this feature particular attentionis directed to the effective manner of attaching the escutcheon plate 66to the side plate 31. As clearly shown in Figures 1 and 5, the plate 66is provided with opposed. perforations 86' and 8'1 which arerespectively arranged to be engaged by a fixed lug 88 and aspringpressed lever 89, both of which are secured to the plate 31.l/Vith this construction in assem- I bling the escutcheon plate inposition, it is merely necessary to insert the portion with the opening86 over the lug 88 and then snap the portion with the opening 87 overthe lever.

; To release the escutcheon, it is merely necessary to press the leverback out of the opening and then'raise the plate to disengage it fromthe lug 88. It will be clear or" course that the detachment of theplates may only be eliected when the knob is detached from the spindle.
